Thorax.— Prothorax yellowish-brown. Dorsum of pterothorax brown with a pair of large black dorsal spots and two narrow black stripes parallel to median carina, each stripe confluent with inner side of dorsal spot. Lateral sides of pterothorax yellowish-brown but mesepimeron with a black oblong spot about mid-height and a black spot below, and metepisternum black around spiracle. Pectoral colour pattern shaped as shown in fig. 4. Legs.— Yellowish-brown. Wings.— Hyaline. Venation dark brown. Stigma brown, its surface granular. Postnodal cross-veins 13-12/12-13 in fore and hind wings, respectively. R3 branching between fourth and fifth Pns or at fifth Pn. Abdomen.— Segments 1 to 6 yellowish-brown; segment 7 becoming dark brown toward apex; segments 8 and 9 dark brown; segment 10 yellow with brown apical margin. Caudal appendages yellow, shaped as described in the key and as shown in figs 14-15. Female (allotype).— Total length ca. 41; abdomen 34.5; hind wing 23.5; costal edge of stigma in fore wing 1.5. Similar to male in characters other than those of sex but labrum brown. Terminal segments of abdomen shaped as described in the key and as shown in figs 26 and 33. Variation.— The male and female paratypes are very similar to the male holotype and female allotype, respectively. The species is peculiar in not having the usual metallic lustre and in having the aged specimens not or almost not pruinosed. Etymology.— The specific name curvatus alludes to the strongly curved male superior caudal appendages.
